Description

Technical Field

[0001] The embodiments of the present invention relate to a horizontal charging device and an application method thereof, and in particular to a horizontal charging device for a precision casting furnace and an application method thereof. Background Art

[0002] As a type of vacuum melting equipment, the vacuum precision casting furnace mainly melts the metal raw materials by induction heating in a vacuum environment, pours them into a mold, cools them under certain conditions, and finally makes the required casting products. It is mainly used to produce advanced high-temperature alloy parts.

[0003] The design and use of the feeding device of the vacuum precision casting furnace has the following effects and influences on the entire production process: First, the feeding device is an important component of the equipment and is indispensable to the production process; second, the operation of the feeding device has an important influence on the production process rhythm of the equipment. Different actions and sequences during feeding take up different times, and the process rhythm needs to be adjusted accordingly; third, the sealing of the feeding device has a certain influence on the vacuum degree of the equipment, and the operation and coordination of the feeding action bring different requirements to the sealing of the equipment; fourth, the design of the feeding device has a certain influence on the maintenance of the equipment. When the equipment is shut down for maintenance, the feeding device of the equipment needs to be maintained accordingly, especially the parts involved in the corresponding actions; fifth, the feeding device has a certain influence on the production intensity and efficiency of the operators. Adjustments to the feeding method will make corresponding adjustments to the operator's shift schedule and coordination.

[0004] Generally, vacuum precision casting furnaces are fed vertically. With the help of the turret mechanism, the equipment can not only feed materials but also measure the temperature. At the same time, optical temperature measurement and thermocouple temperature measurement can be calibrated more accurately. When feeding materials vertically, the height of the equipment has higher requirements on the height of the factory building.

[0005] Many factories built earlier have to take the height of the factory into consideration when planning new equipment. This provides a new idea when the height of the factory is limited. At the same time, it also provides a new way of adding materials to the vacuum precision casting furnace.

[0006] Of course, the horizontal feeding mechanism also has certain usage requirements and standards. The equipment can only be fed once during the feeding stage, and raw materials cannot be added for smelting and pouring during the operation of the equipment. Therefore, the quality of the raw materials required for this smelting and pouring needs to be confirmed before the equipment is operated. Summary of the invention
